Validation failure would make all 20 records and the parent object save
fail in totality. I'm trying to have everything save minus the nested
objects with a certain field value of "i". All other nested objects
with other values save fine.

You could use a validation. That would be the normal method. Then
you can just call save and only the valid ones will actually be saved.

I have a scenario where I have to prevent objects from saving to the
database if they have a certain value and I want to come up with the
optimal way to achieve that.
In my scenario, upon form submit, I will send 20 rows to the update
action in the controller. However, I want to discard the 95% of them
that have a particular attribute value to save database rows.
I'm not sure I want to traverse the hashes:
params[:parentobject][:childobject][:grandchildobject][10][attributes][....
within the update action and loop through the objects and delete them
if they have a particular value.
doing a before_save method within the model being destroyed:
self.destroy if self.status = "something"
doesn't seem to be a good option.
Any other ideas?
